The EAR 834L line preamplifier is designed to complement any of the EAR
834P phono preamplifiers and an EAR power amplifier or, indeed, any
other high quality source or power amplifier.

It has facilities for up to five line inputs, and offers a genuine tape
monitoring circuit, making a total of six inputs. A high quality volume
control is fitted, as well as a panel mounted power switch. Input and
output terminals are gold plated.

Designed by Tim de Paravicini in his usual robust style, the EAR 834L is
the perfect match for any high end system, whether biased towards
analogue or digital. The electronic architecture is minimalist, so that
the absolute minimum sonic degradation takes place. There are three
double triode valves, arranged in a classic 'de Paravicini circuit'.
Special attention has been given to the input circuitry. All inputs are
at the rear of the chassis, on the same circuit board as the selector
switches, which are operated remotely by long control shafts.

The power supply is a unique arrangement; a high quality toridal
transformer feeds a double DC power supply, that provides the
low-tension (LT) heater current, and the high-tension (HT) anode
voltage. It is critical in a preamplifier that both the HT and LT
supplies are pure DC, and free from AC ripple. This is the case with all
EAR products, not just this preamplifier.

The circuit is designed used in such a way as to have a minimum life of five years* continuous operation for the valves.

The preamplifier has more than enough output for any power amplifier,
transistor or valve, and is ideal for driving long interconnect cables
to remotely located power amplifiers.

The unit is available in Classic and Deluxe specification. Deluxe builds
on the Classic's specification with a superior chrome and gold finish,
with extra outputs to facilitate bi-amping systems.
